Claims. (Cl. 173-339) 'I'he invention relates to a plug 'socket by which ber, at least one of which extends' into the bore an electrical connection may bemade merely by II to form an opening. Thesecuts provide conpushing a plug into the bore of a socket member, necting-bars I1 joining the ends of the socket which plug is connected or adapted to be conmember III.

The bottom oi' the U-shaped engaging member 20 is preferably bulged so that it engages the sleeve 21 at all times, as illustrated in Figure. 4, in order to positively assure electrical contact through the U-shaped clamping member to the shell or sleeve and the connecting link 22.

It has been described that the connecting link or wire attaching means 22 is positioned as illustrated in the drawing and engages against the ilange i3 on the socket member I Il. It is obvious, however, that the bracket or panel 32 may be ilrst received upon the socket member I and rest against the flange I3, in which case the connecting link 22 may be received between the nut 30 and the sleeve 21. In this position the major portion of the plug socket will be concealed behind the panel which is advantageous from the standpoint oi appearance. If the space in back of a panel is limited, then the illustrated assembly may be used. One assembly of the plug socket is, however, as eilicacious as the other assembly.

Various modiiications will occur to those skilled in the art in the configuration, composi tion and disposition of the component elements going to make up the invention as a whole, as well as in the selective combination or application oi' the respective elements, and no limitation is intended by the phraseology oi the foregoing description or illustrations in the accompanying drawing.
